This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

* Some parts of this feature may have varying levels of support.

See full compatibility

The Document interface represents any web page loaded in the browser and serves as an entry point into the web page's content, which is the DOM tree.

The DOM tree includes elements such as <body> and <table>, among many others. It provides functionality globally to the document, like how to obtain the page's URL and create new elements in the document.

The Document interface describes the common properties and methods for any kind of document. Depending on the document's type (e.g., HTML, XML, SVG, …), a larger API is available: HTML documents, served with the "text/html" content type, also implement the HTMLDocument interface, whereas XML and SVG documents implement the XMLDocument interface.

Some elements in the document are also exposed as properties:

For each <object> element, its id (if non-empty) is exposed.
For each <img> element with non-empty name, its id (if non-empty) is exposed.

If a property corresponds to a single element, that element is directly returned. If that single element is an iframe, then its contentWindow is returned instead. If the property corresponds to multiple elements, then an HTMLCollection is returned containing all of them.
